WASTE AND OVERFLOW FIXTURE FOR BATHTUBS.

Application lcd July 11,

My invention relates to interconnected Waste and overflow fixtures whichare concealed behind the wall of a bath tub; in some instances beinglocated within the wall of the room in which the tub is located.

IThe main object of my invention is to pro- Vide for the withdrawal andinsertion of the waste valve and its operating'member through the wasteopening and the overflow opening of the fixture, respectively, withoutthe necessity of opening the wall or of dismembering the fixture in anyway, except for the removal of the escutclieon or shield covering theoverflow opening, for such withdrawal or insertion.

A further obj ect of my invention is to provide a waste valve operatingmember of a pliant and/or flexible type, which member is normallydisposed within the overflow pipe and may be withdrawn and insertedthrough the overow opening for the purpose of' adjusting or replacementwithout breaking the joint between said overflow pipe and the tub.

And a still further object of my invention is to provide a pliant rod orstem for operating the waste valve to open position in the form of aclosely `coiled member of spring wire, having a weighted end to engageone end of a lever carrying the waste valve and carrying guiding meanspermanently positioned at suitable points; such pliant weighted memberbeing free to rise and fall within the overflow pipe under the influenceof an operating handle disposed within the tub and which may becentrally located with respect to the overflow opening. The overflowopening is normally closed by a shield or escutcheon having suitableports inthe lower part thereof for the passage of overflow from the tub.

These and other features of my invention are more fully describedhereinafter; reference being had to the accompanying drawings, in which:

bined stem and lever consisting of a series of links, 6a, 6b, 6, 6d, and6", pivotally connected together for movement in one direction, butnormally forming a relatively sti arm for a purpose to be described.yThe link ais in threaded engagement with the pop-'up valve 6,- and a nut7 may be employed to hold the same securely thereto. kThe links 61260,6d and 6e form a lever for the pop-up valve; the fulcrum of whichconsists of' a pin 8, which may be suitably connected, as by riveting,to the link 6d. The link 6*l has a threaded portion Gfupon which isadjustably mounted a panor platform 9, for a purpose to be described;such pan being held in itsadju'sted position by means of a. set screw9a. j

The overow pipe, indicated 10, is connected at its lower end to the Tfitting 5 in the usual manner, and at the upper end to an elbow 11,which in turn is connected to the tub by a sleeve 12, forming theoverflow outlet and fitting within an opening 12av in the wall of thetub. These parts are in perma nent engagement with the tub. The pan 9lat theend of the link lever carrying the popup valve 6 is in. axialalignment with respectv to the overflow pipe and the operating means forthis valve, which engage said pan 9, are

disposed within said overflow pipe 10.

A particular featureof my invention comprises the means for operatingthe pop-up valve by engagementwith the flexible lever thereof. Locatedwithin the overiow pipe 10. is an operating member for the pop-up valve,consisting of a pliant and/or flexible rod or stem of coiled-spring wireindicated at 15, carrying a series of guiding collars 16, which may bebrazed or otherwise secured thereto; each of said guiding collars havinga plurality of arms 16a, loosely fitting within the overflow pipe so asto guide the operating member during its vertical movements but withoutaecting the freerisingand falling tively tosaid flexible stem so as toprovide for the proper movementJ of the latter to operate lthe pop-upvalve. The weight may be locked to the stem`17 by a nut 18a.

The upper end of the pliant operating member 15 has fitted thereto atubular member 19, having an apertured projection 19a for pivotalengagement with Van arm 20, of a crankv21, secured to the end of a stem22, journaled in a support 23, within the overflow opening, and havingan operating handle 24, disposed within the tub. The overflow opening ofthe tub is provided by the sleeve 12, in threaded engagement with anelbow 11, at the upper end ofthe overflow pipe 10. A cross-'bar 25,secured to `the `flange 12b of said sleeve carries the support 23 inwhich the stem 22 is j ourn'aled; said support being also provided witha threaded socket 23, receiving a iianged collar 26 bored centrally forthe :reception of an enlarged portion of the stem 22. These parts willbe enclosed by a shield or escutcheon 27, having openings 27a in vthelower part of its flange for the escape of overflow, and being retainedin place by the flanged collar'26.

The crank member 21 at the end of the stem 22 is provided Vwith an arm31, for engagement withy stop projections 32 and 32a, which may beintegral with the wall of the elbow 11. Then in theraised positiom'asillustrated in the drawings, the operating handle 24 disposed within thetub will. lie in a substantially horizontal position toward the right,looking-in the direction of the arrow a', Fig. 1, (toward the left asindicated by dotted lines, Fig. 2), and tlie'a'rm 31 is in engagementwith the stop projection 32; In

such position the pliant operating member 15 is in the raised position,and the pop-up y valve is seated; Lclosing the waste outlet.

1 Then it is desired to open 'the waste outlet,

the handle is thrown over 180o, until it occupies a substantiallyhorizontal position,

but directly opposite the position it occupied with the pliant member 15in the raised position," and in such changed position the arm 31 willengage the opposite projection 32a. Such actionpushesdown the pliantmember;

fthe weighted end engages the pan-9 at the end ofthe jointed lever forthe pop-up valve, and the latter is moved on its fulcrum to elevate ythewaste valve from its seat.

.The pop=up valve with the links'xb, e seq., is pofisiiicient Iweight to.remainA in the closed position, when the pliant opera-ting rod 15 is inthe elevated position, as indicated in Fig. 1 of the drawings. It willbe under stood, however,ithat when the pan 9 is engaged by the operatingmeans located within the overflow pipe, the link lever will be moved andthe pop-up valve will be raised from its seat in a vertical direction;such valve being provided with fins or guides 6g, which insure suchoperation. Pop-up valves of this type, operating in a substantiallysimilar manner are more or less well knownand, except for certaindetails, this pop-up valve and its link lever forms no part of myinvention.

The pliant and/o1' flexible operating member is removable through theoverflow open ing formed bythe sleeve 12, as indicated in dotted lin-es;such opening being accessible by removing the operating handle 24,collar 26, shield 27, and the cross-bar 25 which provides the journalbearing support for the stein 22 of the operating handle. The popupvalve may be readily removed from the waste outlet, after it has beenelevated; the several links which make up the stem and lever of the sameflexing on their `pivotal connections to permit such action.

An important feature of my inventionl resides in the fact that :due tothe plianey and/or iiexibilityof the operating member disposed in theoverflow pipe, no damage can be occasioned the valve 6 closing the`waste outlet, or the flexibleV lever connected to the same, should auser of the tub happen to stand upon said valve when in the raised andopen position. By having the pan 9 adjustable'with respect to theflexible lever carrying the valve 6, it is possible to maintain said panin central position with respect to the overflow pipe should variationsexist between the centre of the waste opening and the centre of saidoverflow pipe. i
